simple html dom grabbing h1 header

I just learning about simple_html_dom.php, I try to get the h1 content with some class.

<h1 class="entry-title">example for the header</h1>

here the raw html file from the website that i want to get the content.

    <header class="entry-header">
    <div class="entry-meta">
        <span class="cat-links"><a href="https://xxxxx/2016/08/11/xxxxxxx" rel="category tag">News</a></span>
    </div>
    <h1 class="entry-title">example for the header</h1>
    <div class="entry-meta">
        <span class="entry-date"><a href="https://xxxxx/2016/08/11/xxxxxxx" rel="bookmark"><time class="entry-date" datetime="2016-08-11T11:54:07+00:00">11 August 2016</time></a></span> 
        <span class="byline"><span class="author vcard"><a class="url fn n" href="https://xxxxx/2016/08/11/xxxxxxx" rel="author">wndwnrt</a></span></span>          
        <span class="comments-link"><a href="https://xxxxx/2016/08/11/xxxxxxx">1 Comment</a></span>
    </div>
</header>

here my code to get the h1 class="entry-title" content (example for the header)

<?php
 require_once __DIR__.'/simple_html_dom.php';
 $html = new simple_html_dom();
 $html->load_file('https://xxxxx/2016/08/11/xxxxxxx');
 $header_1 = $html->find('h1[class="entry-title"]')->innertext;
?>
<table border="1">
 <thead>
   <tr>
     <th><?php echo $header_1; ?></th>
  </tr>
 </thead>
</table>

when i run the code, the result is error:

Trying to get property of non-object

can anyone tell where is the error? and what i should to do? Thank you very much.

Yes you see that error because you are passing only one argument to the find function.

$header_1 = $html->find('h1[class="entry-title"]')->innertext

now try this:

$header_1 = $html->find('h1[class="entry-title"]',0)->innertext

because you also have to pass the number of the h1 you are trying to get!
